This application claims priority under 35 U.S.C. § 119(e) to U.S. Provisional Application No. 62/156,916, filed May 5, 2015, which is expressly incorporated by reference herein.
BACKGROUNDThe present disclosure relates to a seat, and particularly to a seat included in a vehicle. More particularly, the present disclosure relates to a seat mover system for a seat used to vary an arrangement of the seat.
SUMMARYAccording to the present disclosure, a seat system for use in a vehicle includes a vehicle seat and a seat foundation. The vehicle seat is arranged to support the occupant above a vehicle floor included in the vehicle. The seat foundation is arranged to couple the seat system to the vehicle floor.
In illustrative embodiments, the seat system further includes a seat mover system configured to vary tilt, height, and longitudinal position of the vehicle seat relative to the vehicle floor. The seat mover system causes the vehicle seat to move continuously from one configuration to a different configuration without discrete or separate tilt, height, and longitudinal movements. During the movement, tilt, height, and longitudinal position are all varied together in parallel to arrive at the different configuration. In illustrative embodiments, the seat mover system includes two powered scissor jacks that cooperate together to vary height and tilt of the vehicle seat and two rotational units that allow each scissor jack to pivot about a lateral pivot axis and provide fore/aft translational movement of the vehicle seat.
In illustrative embodiments, the seat system includes a seat mover system arranged to move the vehicle seat relative to the seat foundation. The seat mover system includes a first lift unit configured to provide means for moving the vehicle seat relative to the seat foundation to vary one or both of a height and a tilt angle of the vehicle seat, a second lift unit configured to provide means for moving the vehicle seat relative to the seat foundation to vary one or both of the height and the tilt angle of the vehicle seat, and a rotator unit configured to provide means for moving the vehicle seat relative to the seat foundation to vary one or both of the height and a translational position of the vehicle seat.
In illustrative embodiments, the first lift unit includes a first mover and a first actuator. The first mover interconnects the rotator unit and the vehicle seat. The first mover is configured to expand and contract radially relative to a first pivot axis to cause a front end of the seat mover system to move radially relative to the first pivot axis. The first actuator is connected to the first mover and configured to drive expansion and contraction of the first mover.
In illustrative embodiments, the second lift unit includes a second mover and a second actuator. The second mover interconnects the rotator unit and the vehicle seat. The second mover is configured to expand and contract radially relative to a second pivot axis to cause a rear end of the seat mover system to move radially relative to the second pivot axis. The second actuator is connected to the second mover and configured to drive expansion and contraction of the second mover.
In illustrative embodiments, the rotator unit includes a third mover, second mounts, and a third actuator. The third mover is arranged to move the first lift unit circumferentially about the first pivot axis relative to the vehicle floor. The second mounts interconnect the second lift unit and the seat foundation. The third actuator is configured to drive the third mover.
Additional features of the present disclosure will become apparent to those skilled in the art upon consideration of illustrative embodiments exemplifying the best mode of carrying out the disclosure as presently perceived.

A seat mover system in accordance with the present disclosure is a mechanism configured to adjust a position (fore/aft, tilt, and height) of a seat bottom relative to a vehicle floor. The mechanism adjusts position of the seat bottom in a continuous movement rather than several discrete movements. The seat mover system includes a motorized forward scissor jack mounted on a motorized front hinge pivotable about a horizontal pivot axis on a seat foundation and a motorized aft scissor jack mounted on a non-motorized aft hinge. The motorized scissor jacks cooperate to provide both tilt and height adjustment of the seat bottom. The motorized front hinge and non-motorized aft hinge cooperate to provide fore/aft translation of the seat bottom.
The seat mover system of the present disclosure is configured to reduce or minimize visual impact to occupants of the seat mover system. The seat mover system is further configured to maximize component integration, increase/maximize packaging flexibility and use of space, increase/maximize rear foot space for an occupant sitting behind a vehicle seat including the seat mover system. Furthermore, the seat mover system is configured to eliminate opportunities to damage/destroy shoes associated with rails or tracks included in some vehicle seats.
The seat mover system of the present disclosure integrates fore/aft translation, tilt, and height adjustment into one unit or assembly. A digital user experience is provided to an occupant that allows the occupant to move from one arrangement to another arrangement seamlessly and without discrete, serial adjustments. For example, an occupant can move a vehicle seat including the seat mover system from a forward, lowered position to a rear, raised position in one continuous movement rather than raising the seat bottom followed by a separate sliding movement.
The seat mover system creates a new way to move the seat bottom fore/aft, up/down, and tilt. The seat mover system includes two scissor jacks to create the up/down and tilt movement plus two rotational units that allow each scissor jack to pivot together lateral pivot axes and provide fore/aft translational movement. In one example, four motors are included in a seat mover system that work in unison to provide fore/aft, up/down, and tilt movement of the sat bottom. In another example, three motors are included in a seat mover system that work in unison to provide fore/aft, up/down, and tilt movement of the sat bottom.
The seat mover system of the present disclosure may minimize weight of the overall vehicle seat while providing increased functionality. The seat mover system may also minimize the number of parts needed to provide the desired range and types of motion. The seat mover system may also minimize tooling cost as the seat mover system is less sensitive to tolerance variations. The seat mover system may also use lower grade steel which may further minimize costs.
